7[SX-12/8 Load Check]
Make sure that the load when pulling the Carriage with
Tension Gauge (ST-001) is less than 6.6N (675gf).
(If the load is not the rated value, fix the Carriage motor to
the part where the gear engage the strongest and check the
load again.)
PULL
Backlash Adjustment is done automatically by the strength of the Spring.
However, it is necessary to check the load with the SX-12/8 because the motor torque
of the SX-12/8 is smaller than that of the SX-15.
When the load is bigger than the rated value, the loose-step could occur.
